1 mile=1760 yards
First find the constant speed she was running at
speed=distance/time
to find distance subtract 1760-510=1250 yards
1250/10
with this answer divide it by 10 minutes
(125 yd/m)That will be our speed in yards per minute
Next she needs to make 510 yards in 2.5 minutes based on the info given
In order to complete the mile she will need to run 204 yards per minute
to get 204 just divide 510/2.5
acceleration = final velocity - initial velocity/change in time
For this problem treat your speed as velocity
204-125/2.5
This will be your acceleration needed
be sure to put your units (m/s^2)
In order to pass a physical education class at a university, a student must run 1.0 mi in 12.5 min. After running for 10.0 min (assume constant speed), she still has 510 yd to go. What constant acceleration does she need over the final 510 yd in order to make it?
